Backport haskell#10548: Print info about current project file in use to stderr and ignore the imports by default (haskell#10550)

* Print info about current project file in use to stderr and ignore the imports by default (haskell#10548)

* Print info about current project file in use to stderr (fix haskell#10547)

* only report top-level project config files in the default verbosity

in verbose mode report imported files too

* fix tests

* don't print anything when provenance is empty

* fix tests

* Apply suggestions from code review
